Dietary supplements come in many forms, from pills to energy bars. By law, any product labeled as a dietary supplement has to carry a supplement-facts panel that lists its contents.

In addition to the consumer-focused app, NIH has also created the Dietary Supplement Label Database. Although the database is primarily for researchers and scientists, consumers can use it to search for the ingredients listed on the labels of about 17,000 dietary supplements, both those currently on the market and those that have removed from the market. It will be updated regularly as products are added to the market, undergo formulation changes, and are taken off the market.
